17. Tait uses a 21 foot ladder to climb on the roof of his house. The edge of the roof is 16 feet above the ground. He places the ladder at a 78° angle with the ground. What is the length of the part of the ladder that extends above
the edge of the roof? Round to the nearest hundredth.
16ft
78°

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
